A “flame show” is responsive to an audio input signal such as music. A base unit including an analog base unit controller circuit is arranged to receive an audio input signal and generate an analog control signal that is responsive to the audio input signal. The analog control signal is distributed, by wire or wireless, to one or more flame display units such as a “tiki torch.” Each flame display unit has a fuel source, and a proportional valve for controlling an amount of fuel supplied to a burner. Preferably, the control signal controls a gate terminal of a MOSFET semiconductor device, which in turn is coupled to control current in the proportional valve each each unit. By deploying multiple flame display units, all coupled to the same base unit, all of the flame display units contribute synchronously to the overall flame show.

Methods and systems for a flame display may comprise flowing fuel from a fuel source to a burner via an electric valve fuel passage that includes an electric valve and via a mechanical valve fuel passage that includes a mechanical valve, receiving a flame boost mode request, and adjusting the electric valve to a wide open position. The flame display may further be operated in a music mode in which the electric valve is adjusted based on an audio input or in a standard mode.

An oxyhydrogen torch system includes a gas storage system having an oxygen gas storage container and a hydrogen gas storage container; a first gas line in communication with the oxygen gas storage container; a second gas line in communication with the hydrogen gas storage container; a nozzle connected to the first gas line and the second gas line via a first valve and a second valve, the first and second valves to control gaseous flow through the nozzle, the nozzle having a handle; a trigger extending from the handle and engaged with the first valve and the second valve, the trigger operates gaseous flow through the nozzle; and an ignition to provide heat to gaseous flow through the nozzle; the nozzle operates a torch created by the hydrogen gas and the oxygen gas.

A torch with integral flashback arrestor and thermal shut-off device is provided. In one approach, a torch body includes a passageway of the torch body, and a cartridge assembly disposed within the passageway. The cartridge assembly may include at least one of: a resettable pressure-sensitive device, and a thermal shut-off device, wherein the pressure-sensitive device and the thermal shut-off device are modifiable from a first configuration to a second configuration in response to a pressure or temperature gradient in the torch body, and wherein the second configuration restricts flow through the passageway. The cartridge may further include a check valve disposed along the passageway, for example, within a bore of a bushing, or within a retainer coupled to the torch body at an inlet of the passageway.
